Muscles and Movement

Question 1

What is an Agonist Muscle

Answer 1

The muscle responsible for creating movement at a joint, also known as a prime mover, e.g. the bicep brachii contracting in the upward phase of a bicep curl

Question 2

What is an Antagonist Muscle

Answer 2

The muscle that opposes the agonist providing a resistance for coordinated movement, e.g. the tricep brachii relaxing in the upward phase of a bicep curl

Question 3

What is the Fixator Muscle

Answer 3

The muscle that contract to stabilise an area of the body to enable efficient movement

Question 4

What is an Isotonic contraction

Answer 4

Contraction where the muscle contracts and changes length which will create movement at the joint

Question 5

What is an isometric contraction?

Answer 5

Contractions where the muscle contracts creating a force but no movement takes place

Question 6

What are the 2 types of isotonic contractions?

Answer 6

• Concentric
• Eccentric

Question 7

What is a concentric contraction?

Answer 7

Contraction where the muscle contracts and shortens reducing the angle between articulating bones at a joint

Question 8

What is an eccentric contraction?

Answer 8

Contraction where the muscle contracts and lengthens producing tension
